IPC: B41J2/44
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To make the timing of plotting coincident among plural laser beams deflected on respective mirror surfaces when plural laser beams are deflected by deciding an angle formed by each luminous flux made incident on a deflector with the optical axis of each corresponding scanning lens system. SOLUTION: The same image is divided into four colors and plotted by four laser beams La to Lb, respectively. The images respectively plotted on four photoreceptor drums are finally superposed again and become one image. In such a case, two pairs of scanning lenses 6a and 6b are arranged so that their optical axes may be aligned. Then, the scanning lenses 6a and 6b are not arranged in point symmetry with the rotary axis A of a polygon mirror 5 as center but arranged in linear symmetry with respect to a y-axis being a line crossing at a right angle to the rotary axis A of the mirror 5 and the optical axes 6ax and 6bx of the respective lenses 6a and 6b.  Thus, the angle formed by each luminous flux made incident on the deflector with the optical axis of each corresponding scanning lens system is decided so as to make the timing that each luminous flux scans and forms the image on a surface to be scanned coincident.
